anybody know how to encode a multichannel rmvb ?
Looking around on the Internet those distributed rmvb ripped by others are all 2 channels stero audio even though the sources are 5.1 surround.
As I knew that modern realaudio support 5.1 multichannel audio Who have experiences to encode sources to multichannel rmvb format ? ps I'm not my question is asking in right forum. Please forgive me if I'm wrong. |

Not rocket science. Sample here.
P.S. Their encoders are CBR only. Real Audio fails it, just don't bother and move on to a better format. Their AAC encoder is no better (I don't think they made it 5.1 capable yet). |

I can play that multichannel rm and output to my PC 5.1 speakers correctly.
Then if I have a DVD source with AC-3 5.1 surround how do I converting it to rmvb 5.1 multichannel ? I knew the video part conversion but audio. Recently I spent sometimes studying on it. I had created a rmvb multichannel. But the 5.1 surrounds outputted not correctly. Followings are what I did. It is a DVD source and I used DGAINdex to generate a .d2v file my avs script Code:
# PLUGINS LoadPlugin("C:\PROGRA~1\GORDIA~1\DGMPGDec\DGDecode.dll") LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\UnDot.dll") LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\FluxSmooth.dll") LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\NicAudio.dll") video=mpeg2source("C:\movie.d2v") audio=NicAC3Source("movie T02 3_2ch 448Kbps DELAY 0ms.ac3") video=video.crop(2,0,716,476).LanczosResize(640,480) final=audiodub(video,audio) return final However the rmvb can't output 5.1 surround properly out front left and right speakers have sound on most of the time. I captured the sound card muxer to see the VU meter differences between playing back the rmvb file and the .AC3 file demux from the DVD source. http://vip.cyberec.com/~kaichung1/mixer.htm Last edited by adrianmak; 2007-06-25 at 21:21. |

I donno about any auto apps. I used the command-line Helix Producer, and you have to feed it a 6ch WAV file. It just so happens I saved all the cli stuff I did in those tests, so here ya go.
Code:
"C:\Encoding\Helix Producer\producer.exe" -i "D:\VOBs\Manhole\Manhole 6ch WAV.wav" -o "D:\VOBs\Manhole\Manhole 6ch RA8 Cook.ra" -arq high -eco high -daw -dv -dt -am voice -ad "Nicholi RA Cook.rpad" Code:
